Glass ashtray exploded, much of it still within its own footprint. No cigarette butts to be found.

How hot were the ashes? If there's a significant temperature difference if it's cold outside, then that could shatter the glass.

Mild weather. There were maybe 20-30 butts in the ashtray. I just found it this way in the morning.

This. Also depending on how glass is cooled in construction processes, the molecules of the amorphous solid can take on some weird stress patterns -- prince Rupert's drops are a famous example of this phenomenon. Placing a hot cigarette or cigar face down on the right spot, maybe with a temperature difference to boot, could cause a material failure like this.
it was struck by an airliner at collapsed after burning jet fuel and office supplies compromised the structural integrity of the ashtray

So it was outside overnight? Definitely a temperature change, then.

My guess is that the butts lit up sometime in the night and heated the glass then it popped. The remaining butts burned to ash (causing the burn scars), and blew away leaving no trace.
It's just hard to imagine the butts burning that hot.
Could also be blue ice from a 747, or a visitation from a 5th dimensional being.

It's not like they have to be scorching hot.
Once, my friend took a warm glass out of the dishwasher and poured cold juice in it and it shattered.

Ice.

Maybe it has something to do with all those burn marks on the wood below it? That one in the ring looks kinda fresh. The patterning reminds me of a medium-focus, solar hotspot from a magnifying lens.
